UNITED STATES JEAN B. DAUDELIN, OF FALL RIVER, MASSACHUSETTS.

SHUTTLE.

Application filed April 13, 1923. Serial No. 631,918.

To all whom it may concern:

Be it known that l, J EAN B. DAUDELIN, a citizen of the United States,residing at Fall River, county of ,Bristol, Commonwealth ofMassachusetts, have invented cert ain new and useful Improvements inShuttles, of which the followingis a specilication'.

This invention relates to automatically threading shuttles for use inweft replenishing looms, and involves certain improvements over theshuttle described and claimed in my prior application, Serial No.580,190, filed January 18, 1922, to which reference is made asillustrating the type of shuttle involved herein.

My present invention is particularly di rected to the construction ofthe threader it self, to the end that the shuttle may be quickly andconveniently threaded and that when threaded the weft will be preventedfrom improper escape from the threading eye during the run of theshuttle, and consists in the novel construction, combination, andrelation of parts described and illustrated in the accompanyingspecification and drawings and particularly pointed out in the appendedclaims. Throughout the specification and drawings like referencecharacters are correspondingly applied, and in the drawings Fig. 1 is apartialplan view at the threading end of an automatic loom shuttle ofstandard. type equipped with a threader in accordance with my invention.

Fig. 2 is a side elevation thereof.

Figs. 3 and 4: are side elevations of the threader removed and viewedfrom the delivery and intake ends, respectively, of the threading eye,and

Figs. 5 and 6 are end elevations as viewed from the right and left,respectively, of Fig. 3.

I have indicated at 1 a portion of a loom shuttle of standard type, at 2the shuttlethroat, at 3the threading eye and at 1 the weft carrier. Mythreader is indicated generally at T and is mounted in approximately thelongitudinal axis of the shuttle throat. As here shown the threader is ametallic casting comprising a top wall 5, a depending vertical sidewall6, a bottom wall 7 and an upturned vertical extension 8 defining withsaid walls 5, 6 and 7 an openended recess within which is mounted athread guide 9. The bottom wall 7 has a depending stud 10 adapted to fitwithin a hole formed in the bottom of the shuttle throat and thevertical extension8 thereof is shouldered at one, end as indicated at 12to fitwithin a vertical groove in the shuttle body and key the threaderin the shuttle throat.

- The guide 9 is preferably a helical coil seated in the open-endedrecess of the threader and at its rear end'abutting a narrow shoulder 10formed on the under face of the top wall 5 of the threader. Thisshoulder prevents the weft W from lifting out of the coil during the runof the shuttle. Beyond the shoulder 10 the top wall 5 of the threaderextends as a downturned guide tongue 11 effective in threading to directthe weft from the weft carrier downwardly into the guide coil.

One end of the coil is bent substantially vertically downwardly asindicated at 9, Figs. 4 and 5, to overlie the upturned wall 8 of thethreader, the rear edge of said eX- tension 9 abutting the shoulder 12of said wall. The extensions 8 and 9 and wall 6 are pierced by a hole 13for the reception of the anchoring screw 1 1, Fig. 2, which passestransversely of the shuttle throat from side to side thereof and fixesthe threader within said throat.

Beyond the forward end of the guide coil, the top wall of the threaderis provided with a depending vertical snubbing post 15 disposedsubstantially in line with the axis of the guide coil. Forwardlyof saidguide post 15 and offset laterally with respect thereto, is a downwardlyand rearwardly tapering guide pin 16 formed integrally with the top wallof the threader and terminating short of the lower end of the snubbingpost 15. The wall 6 of the threader is notched, as indicated at 17, Fig.3, to permit the weft to pass laterally from the guide pin 16 "into theintake end of the threading eye. Extending laterally over the threadingeye from thetop wall of the threader, is a downwardly and rearwardlydisposed tongue 18 from which depends a vertical rib 19. The rib 19 isparallel to the longitudinal axis of the threading eye and slightly inadvance thereof. There is a clearance between the forward edge of thetongue 18 and the wood of the shuttle at this side of the shuttle eye,such clearance conlet slot 31 of the eye.

, thenotch 17 into the eye.

stituting an inlet port 18 by means of which the weft, in threading, mayenter the eye 3 from above, the rib 19 terminating short of theoverlying tip of the tongue 18, as indicated at 19, Figs. 5 and 6, topermit the weft to clear said rib in entering the eye. The extremeforward end of the threader at the side opposite the tongue 18 is formedwith a down-turned guide tongue 20.

The threading eye 3 is provided with a vertical inlet slot 21 openinginto said eye from above and'connecting with the port 18, and at itsdelivery end, a pair of guide pins is set through the wood of theshuttle on either side of said eye. Thesepins define the delivery end ofthe eye. The intake end of the eye is defined by the metal of thethreader on either side of the notch 17, the snubbing post 15 beingdisposed substantially in the longitudinal axis of the eye in rear ofsaid notch.

In threading the shuttle, the weft from the weft carrier 4 is drawn intothe space between the outermost turn of the helical guide coil and theanchoring portion 9 thereof, the guide coil being preferably wound in adirection opposite to the unspooling action of the weft so that the weftwill automatically work its way towards the center of the coil. From thecoil the weft passes over the snubbing post 15 and down the guide-pin 16into the'port 18 along the forward side of the rib 19 and into the in-The shuttle is now threaded and the weft runs from the coil directlypast the snubbing post 15 and through Any tendency of the weft to escapeby direct, upward lifting movement is met by the rib- 19, which thusprevents the weft from drawing backwardly along the tongue 18 into theport 18. The

weft is therefore compelled to pass outwardly between the guide pins 22.

Various modifications in the form and construction of my device mayobviously be resorted to without departing from the spirit of myinvention if within the limits of the appended claims.

What I therefore claim and desire to secure by Letters Patent is 1. In ashuttle having a threading eye, a threader mounted longitudinally of theshuttle throat, a tongue overlying the threading eye and defining withthe adja cent portion of the shuttle body a thread inlet port openinginto said eye from above and a vertical rib depending from said tongueand extending above and parallel to the. longitudinal axis of said eyeand constituting a barrier effective to prevent escape of the weft fromsaid eye by an upward lifting movement.
